My invention relates to improvements in Weatherstrip. One of its objectsis to provide an improved all metal Weatherstrip. Another object is toprovide an improved Weatherstrip having a more uniform resilient tensionover a wide range of adjustments, whereby long period of uniformresiliency in use is insured. Another object is to provide an improvedform of metal Weatherstrip whereby improved and continuous close contactis maintained the full length of the joint. Another object is to providenormally for a double sliding or surface contact at the joint. Anotherobject is to provide a Weatherstrip better adapted to exclude wind andwater. My invention also comprises certain details of form andcombination of components, all of which will be fully set forth in thedescription of the accompanying drawings, in which;

The accompanying drawings illustrate the preferred embodiments of myinvention. -As illustrated in Figs. 1, 3, 4, and 5, the Weatherstrip isconstructed of resilient sheet metal and comprises a plane centralsection-15, at one end of which the metal is bent atian angle to'section15 to form a section 16,, andlis then folded upon itself to form asection 17. At the opposite edge of the section 15 is a section 18, bentat an angle to section 15, and the metal then folded upon itself to forma section 19. The free edge 20 of section 19 is preferably slightlycurved or may be folded upon itself to provide a smooth finished edgeadapted to slide freely over the face of the door or window frame.

As illustrated in Fig. 3, the parallel sections 16 and 17 are attachedby a series of nails or screws 21 to a window frame 22, and where thejoint between the frame 22 and the sash 23 is wide or loose, theweatherstrip occupies substantially the position shown in Fig. 3, withthe section 18, pressed resiliently against the face of the sash 23, andthe edge 20 of section 19 pressed resiliently against the face of theframe 22,

so as to effectually exclude wind and water. lVhere the joint betweenthe sash 23 and frame 22 is close as shown in Fig. 4, the Weatherstripassumes substantially the position shown in Fig. 4, in which the section18 is held resiliently against the face of the sash, the edge 20 ofsection 19 is held resiliently against the frame, and also the section15 is bowed so that its curved central portion is held resiliently incontact with the sash. In both positions 3 and 4 the section 17 is alsoheld resiliently against the face of the frame 22 to a greater or lesseX- tent depending upon the extent to which the nails 21 permit thesections 16 and 17 to move relative to the frame, under the strainapplied by the sash to sections 15 and 18. The Weatherstrip is designedto be held substantially rigidly to the frame 22 at the point where thenails are applied. Leverage is applied by the sash, tending to flex theWeatherstrip from its original outline. at the extreme end of section 18where such leverage would be most effective, and where the widest rangeof movement would be capable of taking place. The resilient action ofsection 19 tends to counteract the action of leverage or force appliedto the section 18. which results in the tension required ,to, depresssection 18 toward the frame 22 remaining substantially uniform for allpositions. and at the same time no one of the yielding portions of thestrip is strained to an extent which would tax .its moment of resiliencyand cause it to take a permanent bend or hence the stri tends performits functionsand to retain substantially all of its resiliency for longperiods of useful Sel'VlCe.

In the modification Figs. 2, U, 7, and 8 the Fig. 1, is curved insteadof plane. A section 31 corresponds to the section 16 of Fig. 1, and asection 32 corresponds to the section 17 of Fig. 1; The section 32 maybe in one plane as illustrated in Fig. 1, or itmay be bent to an obtuseangle as shown in Fig. 2, dependingupon the amount of resiliency desiredin the Weatherstrip. A section 33 cor responds to the section 18 of Fig.1, and a seetion lilcorresponds tothe section 19 of Fig. 1. The sectionB Lis preferably curved or folded upon itself at 35 in order to pro--vide 'a smooth edge adapted-toreadily slide alongthe face of'the frame36 in operation. As shown in Fig. 2 the section 34 is bent at an obtuseangle but'may be all in one plane as shown in the section 19 of'Fig. 1.

Fig; 6, illustrates substantially the position of the Weatherstrip whenapplied'to a loose joint between the window frame 36 and a windowsash37," and Fig. '7, illustrates sub stantially the position assumed by thestrip Fig; 2; when applied to a close joint between the sash and frame;Fig. 8, illustrates a position-ofthe parts intermediate of=the positionsshown in Figs. 6 and-7s It will be notedin Figsi6 and 7 that due to theobtuse angle in the section'32 the middle portion of said section doesnot contact with the face a of the frame, and hence that the section 30is given thereby increased resiliency Where it jo-ins'the section 31,and hence is better able to apply uniform resistance to pressure fromthe sash, and to retain its resiliency forlo'ng periods of-service.- Theobtuse angle in sec tion-34l tends in like manner to increase theresiliency of the strip; The sections 17 and '19 of Fig. lare adapted tobe bcnt'to obtuse angles as shown in the corresponding-sec tions 32a-nd3 t'0fFig. 2, and for a like purpose.

In'Fig. 5 l have illustrated ;a strip sinlilar to Fig. 1,l)llt with-asection 170 corre spending-to section 17 of Fig, bent. to an obtuseangle, similar to that shown at 32 of Fig. 2, andsaid stri'papplied tothe'joint between a door frame 40 and a door 41. In Fig; 9, I haveillustrated at 60 the manner in which the Weatherstrip is cut away orrecessed opposite the door latch or lock bolt to enablethe latch or boltto enter its recess in the door frame, and it will-be noted that suchrecessdoes not entirely sever the strip, and in fact does not materiallyreduce itsstrenojth.

and waterproof oint, from top to bottom the door irrespective of thelatch and bolt or bolts.

Another important advantage of my im- 0 section 30 corresponding to thesection-l5 of It will also he notedthat the section 19 still functionsto constitute a continuous wind proved strip is that the section ii or25; rrhere it extends past the edge of the section 16 or iii serves toprevent the united edges of sections 16 and 17 or 31 and 32 from liftingor cocking away from the face of the frame to which they are attached bythe nails 21 at points intermediate of said nails and enables the nailsto be spaced further apart. T he curve in the sections 15 and 30prevents buckling or bending ofthe stripsand secures superior contactwith the opposite face of the joints.

Thea pparatus herein shown and described is capable of considerablemodification within the scope of the claims without departing from thespirit of my invention.
